      Main structure of miniature planetary gearbox

      Shenzhen ZHAOWEI Machinery & Electronics Co., Ltd was established in April 1997 which is State High-Tech enterprise for gear transmission design and manufacture. It provides the total drive solution for customers from design, tooling fabrication, components manufacturing and assembly. Then i will introduce main structure of miniature planetary gearbox.

      Micro planetary gearbox is mainly composed of box, gear, bearing and other additional equipment. We all know that each part has its own important work mission. But what exactly does these parts do in tiny planetary gearboxes. ZhaoWei collected some introductions about the main parts in the micro planetary gearbox. Here we learn about them together. The general structure can be divided into three parts as follows:

      1.Box: box is also an important component of high-power gear reducer. It is very important, all parts are installed on the box, all cases should have sufficient strength sealing and stiffness to ensure that the machine is stable and free of oil leakage. Gray cast iron has been used as the material for making box because of its good casting property and vibration absorption property. In order to facilitate the installation and removal of components, the box is mostly made of horizontal partition along the axis line. The upper cover and the lower box are bolted into one body.

      2.Gear, shaft and bearing combination: the most important component of a micro planetary gearbox, consisting of gears of varying sizes and the mutual bite of bearings, which, according to a certain combination, acts as a deceleration and is fixed through shafts to the interior of the box. Gears and shafts, bearings are forged from high hardness and wear resistant materials, this is the core, so the choice of a good gear for more than a decade there will be no quality problems.

      3.Gear box accessories: in order to ensure the normal operation and other functions of the micro planetary gearbox, in addition to giving adequate attention to the structural design of the gears, bearing combinations and case bodies, there must be other accessories. Generally, fans are used to dissipate heat. There are brake emergencies to stop the operation of the mini planetary gearbox and so on, these are the components of gear reducer indispensable.

      The Design of The Gear Bearing Characteristics

      At present abroad some gears adopt high precision rolling shaft instead of the general sliding bearing, mainly has the following several types:

      (1)Radial sliding bearing.Radial sliding bearing diameter of axle of high speed gear circumferential velocity is higher, told less gear with multiple oil bearing more leaves in the oil bearing wedge.Elliptical bearing, the three oil bearing dislocation, much oil wedge bearing, bearing and so on, even when idle, axis relative to the bearing tile also have great eccentricity, so the stability is good.

      (2)Thrust bearing.Thrust bearing is mainly produced by the helical gear under the axial force and some external axial force (such as motor magnetic field on heart, axial force of the gear coupling, etc.).The structure has a inclined plane and a tilting form.Inclined plane thrust bearing and radial bearing of single structure, is often used to design the thrust bearing, must be both direction have thrust capability.
      The above content "in gear transmission design manual" chemical industry press.

      ZHAOWEI mechanical and electrical through twelve years in the field of gear and gear box professional design, development, production, through the comparison of industry and a lot of experiment data design developed planetary gear box, gear box, gear motor, reduction gear motor, dc planetary gear motor, micro gear motor.
